论文摘要
测量经济活动的地理分布在科学研究和决策中起关键作用。但是，先前关于经济活动的研究和数据具有粗线分辨率或涵盖有限的时间范围，社会经济动力学的高分辨率特征在很大程度上尚不清楚。在这里，我们构建了一个关于中国大陆的经济活动的数据集，即网格机构数据集（GED），该数据集以0.01 $^{\ circ} $ latitude的衡量机构的数量为0.01 $^{\ circ} $。具体而言，我们的数据集捕获了在2005 - 2015年期间在中国大陆注册的大约2550万公司的基于地理位置的开业和关闭。细粒度和长期可观察性的特征使GED具有很高的应用值。该数据集不仅允许我们量化机构的时空模式，城市活力和社会经济活动，而且还可以帮助我们揭示工业和经济发展动态的基本原则。
Measuring the geographical distribution of economic activity plays a key role in scientific research and policymaking. However, previous studies and data on economic activity either have a coarse spatial resolution or cover a limited time span, and the high-resolution characteristics of socioeconomic dynamics are largely unknown. Here, we construct a dataset on the economic activity of mainland China, the gridded establishment dataset (GED), which measures the volume of establishments at a 0.01$^{\circ}$ latitude by 0.01$^{\circ}$ longitude scale. Specifically, our dataset captures the geographically based opening and closing of approximately 25.5 million firms that registered in mainland China over the period 2005-2015. The characteristics of fine granularity and long-term observability give the GED a high application value. The dataset not only allows us to quantify the spatiotemporal patterns of the establishments, urban vibrancy and socioeconomic activity, but also helps us uncover the fundamental principles underlying the dynamics of industrial and economic development.
